The role of vitamin D is more than essential in our body: it ensures many functions of our organism. This vitamin is synthesized naturally in the skin during exposure to sunlight and also provided by certain foods in our diet. It is the best friend of our bones and teeth, but also of our immune system.
What is Vitamin D?
Vitamin D is a fat-soluble vitamin, it dissolves in fat. There are two more well-known forms:
Vitamin D2, which is synthesized by plants.
Vitamin D3, which is produced by animals. It is in this form that we produce vitamin D under the action of the sun's rays on our skin. It then transforms in the liver and kidneys to become active and store in adipose tissue (fat).
What's the point ?
Vitamin D3 plays an important role in the absorption of calcium in the intestinal mucosa. It increases the concentration of calcium and phosphorus in the blood. It facilitates the fixation of calcium on the bones, it improves the mineralization of bones, joints and our teeth.
Am I getting enough vitamin D in my diet?
Vitamin D3 is usually found in fatty fish such as mackerel, herring, tuna, salmon, sardines and trout. It is found in oysters and cod liver. It is also found in egg yolks, butter, milk or certain cheeses. That said, it is present but in a very limited way, which is why we encourage the taking of vitamin D3 supplements on a daily basis.
How much vitamin D should you consume each day?
The quantification of this vitamin is done in international units (IU). If you spend most of your time indoors, without direct exposure to sunlight, it is recommended to take a vitamin D supplement. For people from 5 to 70 years old, it is permissible to take 1000 IU per day. For people with chronic fatigue, seasonal depression or bone disease such as osteoporosis, it is permissible to increase the amount to 1000-2000 IU per day.
